Btw, how does this work on X?  When we wait in waitpid for a
subprocess launched via "M-!", we are not supposed to call the
read-socket hook, so the X messages that tell us to redraw portions of
our frames are not supposed to be redrawn.  If this is what happens,
then the w32 behavior seems to be consistent; if not, what am I
missing here?  Specifically, can you show a backtrace on X from calls
to expose_frame when we are waiting for a synchronous subprocess?
